Sigmoid vs Addepto: overview

Sigmoid

Sigmoid is a San Francisco company founded in 2013 that built its business on data engineering for Fortune 500 consumer brands and later moved deeper into machine learning and generative AI. Its own sales deck describes a hybrid model: each client requirement is classified as either a project or a staff-augmentation need, and augmented staff are billed monthly with a dedicated project manager and engineering manager on top. The company reports more than 200 ML models put into production and over 5,000 data workflows built (per company materials; independently unverifiable). Delivery runs from more than 12 centers across the U.S., Europe, Latin America and India.

Addepto

Addepto has worked on AI and data in Warsaw since 2017, with a strong client base in industrial and automotive companies. KMS Technology, an Atlanta engineering firm backed by Sunstone Partners, acquired it in December 2025. Its collaborative cooperation model puts Addepto engineers alongside the client's own team, and the company has said publicly it is not a body-leasing firm. After the deal, its CEO said 97% of the team are AI engineers.
